RT9811 Product details

Description

The RT9811 is www.datasheet4u.com a micro-power voltage detector with de-glitched manual reset input supervising the power supply voltage level for microprocessors (µP) or digital systems.

Features

low supply current of 2.5µA. The RT9811 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal will last the whole period before VDD recovering. Once VDD recovered up-crossing the threshold level, the reset signal will be released after a certain delay time. A 5% hysteresis splits the rising and falling threshold levels. To pull reset signal low manually, just pull the manual reset input (MR) below the specifie.
